The Argyle Pink Jubilee is a rough pink diamond and the largest rough pink diamond unearthed in Australia. It was found at the Rio Tinto Argyle diamond mine in Western Australia.[2] [3]
Large stones like the Jubilee typically go to museums or end up at high-profile auction houses like Christie's. Christie's has only auctioned 18 polished pink diamonds larger than 10 carats in its 244-year history.[4] The Jubilee was expected to tour internationally before sold at an invitation-only tender.[4]
Originally weighing 12.76carat, the light pink diamond started its cut in Perth in February 2012[3] by Richard How Kim Kam.[5] While being cut, the diamond was found to have "one major internal fault line that could not be overcome."[6] Only roughly formed and polished, and down to 8.01carat, the diamond was donated to the Melbourne Museum.[7]
